Problems solved by technology

This kind of material is light in color, easy to color, and enriches the color system of antistatic coatings. However, when this kind of material is used alone, it has a large amount of addition and poor dispersion stability, which will affect the performance of the paint and its coating. Therefore, it is generally used with carbon Use with materials

Embodiment 1

[0030] The synthesis process of nano zinc oxide fiber is as follows:

[0031] 1mol / L Zn(CH 3 COO) 2 The solution was put into a beaker as a precursor, and the NaNO 2 Add to the precursor, continue magnetic stirring and slowly add NaNO 2 When the final concentration is 3mol / L, stop the dropwise addition and transfer the above solution to an autoclave with a polytetrafluoroethylene liner to keep its filling degree at 80%. React at a constant temperature of 190 degrees Celsius for 1 hour, open the valve to release the pressure under high pressure, and cut off the power supply to allow the autoclave to cool naturally to room temperature. Suction filter and collect the white precipitate. Rinse repeatedly with deionized water to remove excess ions, and dry in a vacuum oven at 90 °C.

[0032] The nano zinc oxide prepared by this method is fiber type, and the aspect ratio is 16:1.

Embodiment 2

[0034] The raw material components of an anti-corrosion and anti-static coating are: styrene-acrylic emulsion 25-30%, nanometer zinc oxide fiber 0.2-10%, zinc phosphate 15-20%, conductive mica powder 10-15%, conductive Zinc oxide 5-10%, paint additives 2-5%, deionized water 15-25%. The coating additives include by mass parts: 0.3-0.5% of NXZ defoamer, 2-3% of ethylene glycol, 0.3-0.5% of 2020 leveling agent and 3-4% of TEXANOL1321 film-forming aid.

Embodiment 3

[0036] Synthesis of heat-reflective heat-insulating anti-corrosion coatings:

[0037] Weigh 1 gram of nano-zinc oxide fiber prepared according to the method in Example 1, add 100 grams of deionized water to prepare a mixed solution. In the state of magnetic stirring, add 1 g of NXZ defoamer, 7.5 g of ethylene glycol, 65 g of zinc phosphate, 45 g of conductive mica powder and 20 g of conductive zinc oxide in sequence. 1000r / min high-speed stirring and dispersing for 1 hour, grinding for 10-20 minutes, ultrasonic dispersion and stirring for 20-30 minutes to obtain pigment and filler slurry.

[0038] Take 210 grams of the above slurry and add 90 grams of styrene-acrylic emulsion, and then add 1 gram of NXZ defoamer, 1.5 grams of 2020 leveling agent, and 5 grams of TEXANOL1321 film-forming aid under low-speed stirring at 300-500 r / min, and add ammonia water dropwise to adjust the pH Value to 8-9. After stirring evenly for 20 minutes, slowly add 0.2 g of ATE-431 thickener to adju...

Abstract

The invention relates to coating and in particular relates to anticorrosion antistatic coating and a preparation method thereof. Raw materials of the anticorrosion antistatic coating comprise a film forming material, nano metal fibers, chemical antirust pigments, fillers and auxiliaries, wherein metal level of the nano metal fibers is lower than level of steel. The anticorrosion antistatic coating has the beneficial effects that nano zinc oxide fibers are adopted; the defect that nano zinc oxide can be easily agglomerated and is difficult to disperse is overcome; conductive fibers have small diameter and great length-diameter ratio, so that a small amount of conductive fibers can form a conductive network structure in coating, and influence on other properties of the coating can be reduced; and contradiction between static conductivity and corrosion prevention property of the coating in the traditional concept is surmounted, and the paint has two functions, namely corrosion prevention and static conduction.

Description

technical field [0001] The invention relates to a coating and a preparation method of the coating, in particular to an anti-corrosion and anti-static coating and a preparation method thereof. Background technique [0002] Static electricity is a natural phenomenon that exists widely in our daily life. There are many ways to produce it, such as contact, friction and so on. The action of the human body or the contact, separation, friction or induction with other objects can generate thousands of volts or even tens of thousands of volts of static electricity. The possible hazards caused by static electricity mainly include: (1) electrostatic discharge can generate sparks, which may cause explosions and fires where flammable and explosive materials exist; (2) cause harm to human health. Therefore, the anti-static treatment of the inner wall of the oil tank is particularly important. [0003] With the rapid development of my country's national economy and petrochemical industr...
